System Problems Rookie Questions, C Rookie Ask a simple question

If you try Norton Partition Magic, you'll see it clear and easy to use, so you can do whatever you want.

With the XP system installed now, this is easy! Most XP discs have these features, especially the hgost system disk! Just like the first installation, first partition and then grid, only grid C disk on the line, other disks can be installed after the system and then enter the system grid!

When you install XP normally, you will be prompted if you need to format the hard drive and partitions. So it's very simple, just use the XP disk to do it step by step.

No need for a lattice Optional: No formatting is required to just move the hard disk space of individual partitions.

Here are the partition tools.

The difference between the third brace plus and without braces is:

add, then the last if statement is in the loop body of the second for loop.

If you don't add it, the last if statement is outside the loop of the second for loop.

Obviously, the for loop is to judge that the condition is met before executing the loop body, and if it is not satisfied, the loop is terminated.

For the second for loop, the condition is j<=m.

Now let's trace the whole process of the parenthetical loop.

In the loop, the value of j increases from 2, and when j<=m, the last if statement is judged to be false, and the subsequent printf will not be executed.

When j=m+1, the condition is no longer satisfied, the loop body is not executed, but the loop is directly exited. In this case, the last printf statement will not be executed.

As a result, the final printf will never be executed.

And if you don't put parentheses. The last if will only be judged after the for loop is finished.

If the break has never been executed, then the for loop exits the loop only after the end of the loop. This means that there is no divisor of i in 0 to m; At this point, from the above analysis, we know that j at the end of the cycle is exactly = m+1At this time, if you make the last if judgment, it will be judged to be true, and the following printf statement will be executed.

If the break statement is executed in the middle of the process and the for loop ends, it means that there is an divisor of i from 0 to m. In this way, if the for loop ends early, the value of j will not increase to m+1, so the judgment of the last if statement will not be satisfied, and the final printf. will not be executed

This makes it possible to output the prime number correctly.

When j=m+1, the loop ends, which means that the self-divisor from small (greater than 1) to large is itself, and after putting curly braces, it can't get in so it can't be displayed.

Such nesting is not supported.

Because you only have 2 in total.

I don't think you're clear about it, so it's not good to suggest it casually!

Since your classmate has the ability to install the system for you, it is the right solution to ask him for help again, because he did the system, and he knows best what he has done! The so-called bell also needs to be tied to the bell.

Another question is the merchant installed genuine win7,If so,It is recommended to restore win7 to use well,Some software is not very compatible is normal,Besides, the software is developing so fast,Soon it will be compatible! You shouldn't give up win7 for this reason.,Especially if you're playing,You'll find that a lot of effects can't be fully displayed in win7! So it is also recommended that you find a merchant and ask them to install a win7 (positive) flagship version for you, most merchants will be willing to have the resources.

- Another suggestion for you is,Don't get any one-click restore,Ghost this software is easy to learn.,As long as you're willing to take the time.,Learn to make your own system backup is the right way!

- It is estimated that the one-click restore is made by the merchant for you.,If so,Even if the restore is broken.,The ghost backup file inside is there.,It's just that it's stored on the hard disk.,If you really don't want it.,You can find it and delete it.。

-Find more of your classmates to see the actual operation for you, and there will be an image after watching it, so that you will have a foundation when you have to do it yourself in the future. After the system is generally done,Don't change it without a big problem,Seriously,If the merchant gives you a genuine win7 and you dispose of it,It's a bit silly。
